**** Used to bring the entire world up-to-date. It flushes pending output to the display and waits for the server to process the output and return errors or events, handles all pending events of any sort and repeats this set of operations until there are no pending events, no pending handlers and no operations still outstanding ( from Tk man page)
**** Same as update, but no new events or errors are processed - only the when idle handlers are invoked.
